Helpful Tips
- Choose Overripe Bananas: They are sweeter and mash more easily, enhancing the banana flavor.
- Don’t Overmix: Mix the batter until just combined to keep the brownies tender.
- Brown Butter Carefully: Watch the butter closely as it browns to avoid burning.
- Cool Before Frosting: Ensure the brownies are only slightly warm before adding the frosting to prevent it from melting.
Substitutions and Variations
- Nuts: Swap walnuts with pecans or almonds for a different nutty flavor.
- Gluten-Free: For a gluten-free option, substitute the regular flour with a gluten-free all-purpose flour mix.
- Dairy-Free: Substitute dairy-free butter and sour cream alternatives.
